Pesticidas organicos

Los pesticidas orgánicos son pesticidas hechos de sustancias naturales o mezclas caseras hechas de jabones orgánicos y/o etanol.

Los pesticidas orgánicos pueden permitir a los agricultores controlar plagas y enfermedades en las plantas sin recurrir a pesticidas convencionales. Esto no significa necesariamente que sean más seguros de usar. Los presticidas orgánicos pueden ser tan dañinos para la fauna/flora del medio ambiente como los pesticidas químicos. ^[1] Sin embargo, en comparación con los pesticidas químicos, el medio ambiente puede descomponerlos mucho más fácilmente.

Esta página enumera los pesticidas orgánicos que puede fabricar localmente y analiza contra qué plagas/enfermedades son efectivos. Las recetas en sí se pueden encontrar en recetas de pesticidas orgánicos .

Use pest-specific pesticides

La clave para usar pesticidas apropiadamente es usar pesticidas que son (tanto como sea posible) es saber exactamente cuál es el problema o plaga/enfermedad que está causando problemas. Algunos problemas pueden no ser plagas/enfermedades, sino deficiencias de nutrientes . Si se trata de una plaga/enfermedad, trate de identificarla antes de usar pesticidas.

Aquí hay algunos recursos que pueden ayudarlo a identificar el problema:

• Manual de enfermedades de las plantas de Texas : este excelente recurso tiene una lista de cultivos comunes en Texas y plagas y enfermedades comúnmente asociadas. Fotos incluidas
• Una guía de enemigos naturales en América del Norte : lista de depredadores con imágenes. ¡Guía útil, pero es posible que se requiera algo de latín!
• Identificación de plagas domésticas y estructurales: siga la clave para identificar plagas comunes.

List of organic pesticides

Nota: Cuando una planta se nombra como plaguicida potencial, esta planta de la que se deriva la sustancia a menudo se puede intercalar para tener el mismo efecto plaguicida.

pesticida organico	¿Contra qué plagas y enfermedades?	Notas y artículos académicos
Bicarbonato de sodio, bicarbonato de sodio	hongos, mildiú polvoroso, mancha negra rosada, antracnosis, mildiú velloso, mancha marrón	http://web.archive.org/web/20100507163427/http://attra.ncat.org:80/attra-pub/bakingsoda.html
semillas de gato negro	pulgones, orugas	?
mixtura bordelesa	pulgones, orugas	Bordeaux mixture is a mixture of copper sulphate and slaked lime. It works preventively to fungal attacks. It is a very old mixture. The copper ions on the leaf prevent the germination of the fungal spores and the calcium also increases the pH.
Chinaberry leaves	Aphids, caterpillars	?
Cornmeal, cornmeal solutions	yellow leaves on photinia, brown patch, algae in seedlings, leaf spots on roses	?
Confusion lures	?	?
Citric acid	?	?
copper sulphate /copper hydroxide /copper oxide	?	?
Dead bug spray	Any insects	http://web.archive.org/web/20080821124420/http://wiwi.essortment.com/homemadeorgani_renu.htm
Diatomaceous earth	?	?
Garlic, garlic solutions, garlic oil	Aphids, thrips, mosquitoes, onion flies, rabbits (on potatoes), other chewing and sucking insects	When using garlic on soil with thrips, it will cause the thrips to come to the surface. Once they are at the surface, fermented water/plant mix (from stinging nettle) can be used. Garlic can also be intercropped to repel similar insects
Ethanol	Mealy bugs	?
Human/animal urine	Aphids, caterpillars	Has dual use as it acts both a fertiliser and a pesticide
Jojoba oil	?	?
Kaolin Clay	Protects mainly against insects, but also some diseases. May also reduce damage from birds since there are less insects to attract them.	Non toxic to humans, and not known to hamper activities of beneficial insects such as honey bees.
Milk, milk solutions	Mildew, blight	Abstract, Crop Science (Vol. 18, 1999, pp. 489-92)
Neem leaves, neem oil	Aphids, Bull worm, caterpillars	Neem can have multiple functions such as for medicinal use. See Neem article
Paraffinic oil	?	?
Paprika, hot pepper	cats, dogs, insects, bugs, snails and snails (on leaves)	often used in combination with spearmint to improve effectiveness
Potassium bicarbonate	?	?
Pyrethrum	?	this plant-based insecticide is a strong neurotoxin to all cold-blooded creatures. It is virtually harmless to warm-blooded creatures however. Pyrethrum breaks down within 48 hours. Other plant-based insecticides are Koppert Rotenon and Koppert Plantschoon.
Rock meal	bacteria, fungi, some insects	Seaweed calcium, basalt and lava meal increase the acidity which protects crops from bacteria/fungi. The fine rock meal has a dehydrating effect and damages the wax layer of many insects. By dusting or spraying, the plants are covered with a thin layer of dust. Treatment is done in the evening and it should not rain for 12 hours (maximally done for up to 2 times per month). Dosage= 250g/are.
Spinosad	?	?
Silicic acid	?	spraying of this increases the plant defenses
Soap, soapsuds, soap solutions	Slugs, aphids	Solutions can be sprayed on any plant leaves or used near affected plants
Spearmint	insects, bugs, chewing insects	often used in combination with hot pepper to improve effectiveness
Sulphur	several fungi (mildew and scab)	one sprays pure sulphur. It is harmless to humans and animals. Bio-S is a commercial sulphur product.
Tobacco, nicotine, nicotine solutions	Caterpillars, aphids, many types of worms, fungus gnats, symphylids, centipedes, root lice, other underground pests	Solutions can be sprayed on any plant leaves or used near affected plants
Tomato leaves	common insects, blight	[1]
(Wood) ash	Common insects	repellant substances as wood ash can be placed around the edge of vegetable areas to reduce pests. It is presumed that this materials is avoided by insects and small rodents Herbal repellents from Soberbio Veto
Soberbio Veto	Rat, Lizard, Roach, Snake	. This is formula with organic extracts of Margosa, eucalyptus, holy basil, clove oil etc do it yourself technique with convenience of just keep the extract in a area and with the diffusion in air it irritates and repels pest.
